When the population density of wild boars increases, simply enclosing the fields with a protective fence is likely to result in the fence breaking and intrusion.
This is because if only defensive measures are taken, wild boars become less wary of humans and become bolder and bolder. The solution is to increase hunting pressure through capture. Box traps and tie traps are often used for capture.
Among those methods, we will introduce the characteristics, how to set and tricks of box traps for wild boars.
Advantages of box traps
The advantage of box traps is that they are also safe. Since the captured animal can be stabbed from outside the box, there is little risk of injury from the animal.
Also, if you capture a beast other than the target, such as a hound, you are less likely to injure yourself. Because wild boars have tremendous power to rage, it is not uncommon for wild boars that have been captured to rip off their legs and escape.
There are many cases where it is difficult to deal with after capture. On the other hand, box traps won't escape after being captured unless the door is lifted, so you can deal with them with plenty of time to spare.
One of the strengths of box traps is the large number of traps that can be captured at once. In the case of tying traps, only one animal can be captured per trap, but with box traps, it is possible to capture several animals at once.
Point to set a box trap
To set a box trap, you first need to decide where to place it. It is not possible to constantly change the location because it needs to be acclimatized by feeding. Therefore, choosing a location is very important. If you are worried about it, it is better to install it in a place that satisfies the following three conditions.
1. flat place
Due to its shape, box traps are naturally more stable when placed on a flat surface. If it is unstable, beasts that try to enter the box trap to eat food will be alarmed. Especially in the case of wild boars, if the footing is unstable, they will run away immediately, so choose a place that is not wobbly as much as possible.
Also, if the door is tilted, frictional resistance will cause the door to move slowly, and in the case of box traps that are not sturdy, the frame may be distorted and the door may not fall.
2. A place where there are many traces of wild boars
Box traps are unnatural at a glance, so wild boars are always wary of them at first. It takes time to get rid of their vigilance, but even if you set a box trap in a place where wild boars don't approach in the first place, the result is that they will only be wary and won't even come near.
Based on the tracks left by wild boars (footprints, food tracks, feces, nut tracks, etc.), look for animal trails that they often travel. Also, before setting up a trap, try sprinkling bait on the area where the bite is attached to see if the animal will come and see if it reacts.
What the wild boar eats changes depending on the place and time of year, but it's a good idea to read it and look for traces. (For example, ``It seems that wild boars have been eating chestnuts around here since autumn. There must be bite marks in the forest over there, where there are many chestnut trees.'')
In addition, it is a target because wild boars often appear in the vicinity of the wild boar's living area and playground.
3. Locations that are easy to transport and look around
Box traps for wild boars are quite heavy, so it is quite difficult to carry them to places where you cannot drive.
If you choose a place that is difficult to transport, it will take a lot of effort not only at the time of installation but also after that. Also, after installation, it is necessary to look around the trap every day, so it is important to choose a location that is easy to access.
When making patrols, even if you haven't caught any prey, don't forget to check the fallen vegetation and footprints around the box trap you've set up to make it easier to notice changes in the beast's behavior.
Q. Should it be avoided to install continuously in the same place?
Some people say that even if traps are caught in the beginning, the surviving boar learns and gradually becomes harder to catch. On the other hand, some people say they have been caught repeatedly in the same place and in the same box trap for many years.
I've heard of some cases where one trap takes place twice in the morning and evening. It seems that there are differences depending on the region and year, but basically it seems that as long as the beast is infested, you can catch it in the same place and in the same box trap without any problems.
In order to lure the boar inside the box trap, it is necessary to let go of its vigilance over time while continuing to feed it. During the "break-in" period to let go of the wariness, it is important to stay away from the traps as much as possible when feeding, to patrol efficiently, and to leave as few traces of humans as possible.
Larger individuals have survived for many years, so they are more cautious and it takes days to lure them. Take your time and don't panic, read the movements of the beast and act accordingly.
type of baitAs for the type of bait, rice bran should be the main ingredient. Rice, sweet potatoes, fruit, sake lees, and wine are sometimes combined. Chop potatoes and fruits in advance.
Rice bran may be washed away by rainwater, so it is convenient to bring replacement rice bran or a shovel for replacement work when you go around. In addition, it is a good idea to bring kick strings and tools for re-upholstery in case you need to re-upholster the gimmick.
*If the crops grown in the surrounding area are used as bait, even individuals that previously did not recognize the crops as food will now recognize them as food, which may increase the damage. Avoid
how to spread food
Bait should be placed at least 10 meters away from the trap and scattered towards the trap. At first, they will only eat food that is far away from the trap, but as you continue feeding them, they will gradually eat food that is closer to the trap.
During the break-in period, keep the door of the box trap up so that it does not fall off, letting the target off guard. Once you're eating close to the entrance of the box trap, arm the trigger to capture the target.
Q. Where in the box trap should the bait be wrapped?
A: For single door type
In the case of a single-door trap where only one side of the box trap is a door, put a kicking string at the back and put a lot of bait near it so that even a large individual can fully enter the trap before the trigger is activated. Let's scatter it.
When the target tries to eat the bait in the back, make sure to touch the kick string.
B: Double door type
There are doors on both sides of the box trap, and in the case of a double door type where you can enter from either side, you can enter from which door by putting a kick string in the center of the box trap and scattering a large amount of bait around it. Make sure that the beast also touches the kick string.
Q. Should I choose single door or double door?
In the case of double doors, if you think about it from the perspective of a beast trying to enter the trap, there is no wall at the end, so it will be less likely to be guarded.
Therefore, double doors tend to lure prey into the trap more easily than single doors, shortening the time it takes to enter the trap. On the other hand, in the case of a single door, there is only one entrance and exit, so the probability that the prey will escape at the moment of capture is low.
In the case of double doors, you can close one door and use it as a single door, so if you are wondering which one to choose, you should choose double doors.
Box traps are the most popular method of trapping, and are highly effective and safe. Even if you are inexperienced, if you can set up and feed them properly, you will definitely be able to catch them.
In the case of ready-made products, the price is about 80,000 to 100,000 yen.
If you are considering installing a box trap for the first time, or if you are thinking of purchasing a new one, it would be a good idea to contact the local government in the area where you plan to install the trap.
